Background/Objectives: Asymmetries in force production, characterized by vertical ground reaction forces (VGRFs), during lower-limb bilateral movements such as deadlifting and squatting, are considered biomechanical risk factors for injury. Real-time biofeedback has been used to modify lower limb production but typically implements monitors. The purpose of this study was determine the effect wearable visual (WVBF) on asymmetries VGRFs knee joint angles rate perceived exertion (RPE) deadlift...

Rolling is an important part of infant motor development and largely affected by experiences surroundings. The purpose this study was to determine how inclined mechanical environments affect muscle activation during previously defined coordinated rolling movements. results demonstrate that utilization (age: 6.5 ± 0.7 months; 23 M/15 F) differs while achieving the same movements on a flat surface compared four representing range inclines which infants are commonly exposed. Thus, milestone...

BACKGROUND: Motion analysis has great potential for quantitatively evaluating dental operator posture and the impact of interventions such as magnification loupes on subsequent development musculoskeletal disorders. OBJECTIVE: This stu

Abstract Infant positioning in daily life may affect hip development. While neonatal animal studies indicate detrimental relationships between inactive lower extremities and development dysplasia, no research has explored infant biomechanics experimentally. This study evaluated joint position lower‐extremity muscle activity of healthy infants common body positions, baby gear, orthopedic devices used to treat dysplasia (the Pavlik harness the Rhino cruiser abduction brace). Surface...

Work-related musculoskeletal disease (MSD) is the second leading cause of disability globally. Ophthalmologists widely report MSDs in neck (70%) and back pain (40-80%). Our study intended to identify prevalence among pediatric ophthalmologists.Pediatric ophthalmologists self-reported chronic pain, instrumentation used, years practiced, surgeries performed, work schedule/environment modifications due MSD, treatment for MSD via an anonymous online survey. Statistical analysis responses...

Inertial measurement units (IMU) are increasingly utilized to capture biomechanical measures such as joint kinematics outside traditional biomechanics laboratories. These wearable sensors have been proven help clinicians and engineers monitor rehabilitation progress, improve prosthesis development, record human performance in a variety of settings. The Valor IMU aims offer portable motion alternative provide reliable accurate when compared industry gold standard optical cameras. However,...

Total hip arthroplasty (THA) is a common and effective surgical procedure that allows patients with osteoarthritis to restore functional ability relieve pain. Sit-to-stand transfers are demanding tasks during activities of daily living performed more than 50 times per day. The purpose this systematic review obtain comprehensive understanding biomechanical changes sit-to-stand after THA.Relevant articles were selected through MEDLINE, Scopus, Embase, Web Science. Articles included if they met...

Musculoskeletal computational models provide a non-invasive approach to investigate human movement biomechanics. These could be particularly useful for pediatric applications where in vivo and vitro biomechanical parameters are difficult or impossible examine using physical experiments alone. The objective was develop novel musculoskeletal subject-specific infant model hip joint biomechanics during cyclic leg movements. Experimental motion-capture marker data of supine-lying 2-month-old were...

BACKGROUND: Absent or abnormal fidgety movements in young infants are associated with subsequent diagnoses of developmental disorders such as cerebral palsy. The General Movement Assessment (GMA) is a qualitative clinical tool to visually identify absent stage, yet no quantitative measures exist detect activity. OBJECTIVE: To determine whether correlation exists between Center Pressure (CoP) measurements during supine lying and age. METHODS: Twenty-four healthy full-term participated the...

Abstract While many factors contribute to development and subsequent correction of developmental hip dysplasia (DDH) in infants, positioning muscle activity play a significant role. Lower‐limb restrictive extension positions, such as with swaddling, are detrimental for development, some baby gear leads reduced lower limb activity. Yet how impacts position during wear remains unclear. The purpose this study was compare the Graf's alpha angle femoral head coverage healthy infants mild DDH...

OBJECTIVES/GOALS: One in six children the U.S. has a Neurodevelopmental Disability (NDD). Prechtl’s General Movement Assessment (GMA) is qualitative predictor of early motor dysfunction. However, no quantitative biomechanical assessment exists to more accurately identify all patients with NDD. METHODS/STUDY POPULATION: With UAMS IRB approval, as part larger study, healthy infants were filmed while lying supine on force plate for 2 minutes. We studied 12 full-term (gestational age: 38.9±1.5...
